Sunan Abi Dawud 1344
Prayer (Kitab Al-Salat): Voluntary Prayers
On The Night Prayer
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا سَعِيدٌ، بِهَذَا الْحَدِيثِ قَالَ : يُسَلِّمُ تَسْلِيمًا يُسْمِعُنَا كَمَا قَالَ يَحْيَى بْنُ سَعِيدٍ .
The above tradition has also been transmitted by Yahya b. Sa'id to the same effect. The version adds the words: "He uttered the salutation so loudly that we could hear it."
